When we talk about 0-days, we usually mean unpatched software vulnerabilities. But what do you call it when attackers exploit a product’s legitimate features — features working exactly as designed — to build a near-perfect social engineering chain?

In this episode, we break down a phishing operation that weaponized Ledger’s own Recover feature to send real verification emails from Ledger’s servers, turning the company’s trust infrastructure into the most convincing part of the scam. This isn’t a code vulnerability. It’s a feature-level 0-day: the attackers found that Ledger’s verification workflow could be triggered externally and repurposed as a trust anchor inside a voice-call social engineering attack.

We’ll walk through how Rexxfield’s former founder Mike turned the tables on the scammers during a two-hour phone call, the seven-stage phishing kit our threat hunters dissected, and the triple-redundant seed phrase exfiltration system that captures your wallet keys before you even click submit.
